Help with question 11.79

Postby Kenan Kherallah 2C » Wed Jan 09, 2019 9:43 pm

11.79 A reactor for the production of ammonia by the Haber process is found to be at equilibrium with PN2 3.11 bar,
PH2 1.64 bar, and PNH3 23.72 bar. If the partial pressure of N2 is increased by 1.57 bar, what will be the partial pressure of each gas once equilibrium is re-established?
I have no idea how to approach this problem

Since you have a change in the system (partial pressure of N2 is increased -> concentration of N2 is increased/more N2 is added), it's a hint for you to use an ICE table. Even though Dr. Lavelle showed it to us with concentration, it can also be used with pressure, since mole ratio and partial pressures are proportional. I hope this helps!
